QNAP SS-439 PRO and SAMSUNG Spinpoint M8 HN-M101MBB 1TB Hard Drive 9.5mm

I just upgraded my QNAP SS-439 Pro with 4 x 1TB SAMSUNG Spinpoint M8 HN-M101MBB drives. I decided to wait for these since they are the 9.5mm height disks vs. 12.5mm and wanted to maintain good air flow as much as possible. I upgraded from 4 x 500GB Samsung M7 HM500JI drives.

I checked the alignment since these are 4k advanced sector drives and it looks like QNAP firmware version 3.4.3 Build 0520T correctly aligned the drives:

[~] # fdisk -ul /dev/sda

Disk /dev/sda: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors
Units = sectors of 1 * 512 = 512 bytes
   Device Boot      Start         End      Blocks   Id  System
/dev/sda1              40     1060289      530125   83  Linux
/dev/sda2         1060296     2120579      530142   83  Linux
/dev/sda3         2120584  1952507969   975193693   83  Linux
/dev/sda4      1952507976  1953503999      498012   83  Linux

I am guessing this also applies to the SS-839 Pro unit since they are the same except for the 4-bay vs. 8-bay design. It's great to finally start catching up to the 3.5" units. I have 2746.27GB of usable space in RAID5 and EXT4.

Now on to the pics:
